In general. referring to Figures 1 and 2, the machine includes a framework and housing, generally indicated at 40. on which is mounted a pair of pouncing pads, generaly indicated at 42 and 44. These pouncing pads are mounted on shafts by which the pads are reciprocated in opposite-phase relationship with respect to e ch other about their longitudinal axes. Pouncing pads 42 and 44 are so mounted that they may be moved toward and from each other or into and out of pouncing 7' position by mechanism to be described hereinafter.- A hat for the pouncing pads and hat together with other mecha- Figure 8a is a perspective view of castings forming a 3,

support, generally indicated at 46, is mounted on a tower, genera ly indicated at 48, which, together with the su port 46. is movable toward and from pouncing pads 42 and 44 (Figures 1 and 3). Movement of the tower 48 toward and from the pouncing pads moves the brim of a hat mounted on support, 46 into and out of pouncing position between the pouncing pads.

A control lever, generally indicated at 50. is movable forwardly and backwardly with respect to the machine, and in addition to other functions to be described hereinafter, controls the movement of hat support 46 and pouncing pads 42 and 44 into and out of pouncing position. A control knob 52 (Figure l) is connected by mechanism to be described hereinafter to pouncing pad 42 so that the user of the machine, by setting this knob, may control the degree of pressure with which pad 42 is pressed toward pad 44 and thus control the amount of pouncing done by the pads during any given pouncing operation.

Another control knob 54 (Figure 2) is mounted on the right-hand side of the machine and is connected to suitable mechanism to be described hereinafter so that the user may be setting knob 54 control the number of revolutions made by hat support 46 before any given pouncing operation is automatically stopped. When a given operation is ended by the mechanism associated with knob 54, pouncing pads 42 and 44 automatically separate, tower 48 moves to an upright or non-operative position, as shown in Figure 2, and control lever 50 moves to an inoperative position or the position it occupics in Figures 1 and 2.

The framework of the machine is composed of five main castings, namely, a base casting, generally indicated at 55 (Figure 3), a front casting, generally indicated at 56, a rear casting, generally indicated at 58, a head casting, generally indicated at 60, and a casting, generally indicated at 62, which supports the pouncing pads and certain other mechanism associated with them. Front and rear castings 56 and 58 are connected at their lower ends to base casting 55 in any suitable manner, such as by screws 64, and head casting 60 is connected to the upper ends of castings 56 and 58 by screws 66. Casting 62 is connected to head casting 60 by screws 68. The open sides of the machine are closed by plates "i and 72 (Figures 1 and 2) in any suitable manner, such as by screws 74 and 76.

Hat support 46 (Figure 12) is mounted upon a shaft, generally indicated at 78, which in turn is rotatably mounted on tower 48. The upper section 78a of shaft 78 is of smaller diameter than the center section 7811 of shaft 78, thus providing a shoulder 78c. Hat support46 includes a plate 46a having a hub 46b formed thereon through which a hole 80 extends. This permits hat support 46 to be mounted on section 78a of shaft 78, the lower face of hub 46b engaging shoulder 78c. Support 46 is keyed to shaft 78 by key 82 and is held in position on shaft 78 by means of screw 84, which acts through cap 86 to hold support 46 in position. Hat support 46 is provided with a pin 88, which, together with cap 86, forms the locating pins on which the hat block (not shown) is mounted.

Shaft 78 has a section 78d of reduced diameter on its lower end to form a shoulder 78e. Shaft 78 extends through a combination thrust and radial bearing 92, shoulder 78c abutting against the upper surface of the inner raceway of this hearing. Bearing 92 is held in position in a recess 48a in the lower end of tower 48 by a retaining ring 94 and screws 96. The upper end of shaft 78 is mounted on sleeve bearing 90. Thus, shaft 78 and support 46 are rotatably mounted on tower 48.

The lower end of tower 48 is connected to a casting, generally indicated at 98 (Figures 6, 7, 7a, and 12), by means of screws 100 which pass through a flange 4811 (Figures 1 and 6) formed on the lower end of tower 48.

Casting 98 is pivotally mounted on the machine to permit tower 48 to move toward and from the pouncing pads 42 and 44 (Figures 2 and 3), and includes a tower supporting section 98a (Figures 7, 7a, and 12) which act as the housing for a helical gear 102 connected to the lower end of shaft 78 by means of pin 104. Casting 98 also includes a tubular section 98b which is pivotally mounted on the machine on sleeve bearings 106 and 108 mounted in casting 110 (Figures 7 and 7b) and casting 112.

Casting 110 (Figure 7b) is provided with a flat face 110a which abuts against a boss 60a extending rearwardly from the forward end of head casting 60. Casting 110 is connected to head casting 60 by means of screws 114 (Figures 6 and 7). Casting 112 (Figures 7 and 7c) is composed of three sections, namely, section 112a for supporting casting 98, section 11211 for supporting the timing mechanism associated with knob 54, and a section 1120 for supporting the control shaft connected to control handle 50 (Figure 2). Casting 112 is connected to the machine by connecting the forward face 116 of section 112a (Figures 7 and 7c) by screws 117 and to front casting 60 by means of asupporting bracket 118 extending forwardly from section 112c and connected to the rear face 110b (Figures 7 and 7b) of casting 110 by screws 119. Bearings 106 and 108 (Figure 7) support section 98b of casting 98 so that the axis about which casting 98 pivots is transversely positioned with respect to the machine. Thus, casting 98 mounts tower 48 so that hat support 46 (Figures 2 and 12) moves in a plane toward and from the pouncing pads 42 and 44.

Hat support 46 (Figure 3) is driven by a motor 120 which is mounted on casting 56 by means of bracket 122. Motor 120 acts through a pulley 124 mounted on its drive shaft 126 (Figures 4 and to drive pulleys 128 and 130 through belt 132. The hub of pulley 128 is mounted on the lower end of a shaft 134 (Figures 4 and 8) and connected thereto by a pin 136. Shaft 134 is mounted within the downwardly extending portion 138a of a casting 138 (Figures 8 and 8a), the upper end of which is connected to casting 110 by means of screws 140 (Figures 4, 7 and 8). Section 138a (Figures 8 and 8a) of casting 138 is of tubular shape, and shaft 134 is mounted within section 138a by means of combination thrust and radial bearings 142 and 144.

The outer raceway of bearing 142 is mounted within an annular recess 1381: in casting 138 and is held in position therein by means of a retaining ring 146 and screws 148. A sleeve 150, mounted on shaft 134, extends between the inner raceway of bearing 142 and the inner raceway of bearing 144 to hold bearing 144 properly positioned within casting 138. Shaft 134 is held in assembled relationship with respect to bearings 142 and 144 by means of the hub of a worm gear 152 connected to shaft 134 by means of set screw 154.

Worm gear 152 (Figures 7 and 8) engages and drives a gear 156, which is mounted on and keyed to a shaft 158 by key 160. Shaft 158 is rotatably mounted within section 98b of casting 98 (Figures 7 and 7a) by means of radial bearing 164 and sleeve bearing 162. A worm gear 166 is mounted on the center section of shaft 158, is keyed thereto by a key 168, and its right-hand end abuts against a shoulder 158a formed on shaft 158 by reducing the diameter of the left-hand portion of the shaft. Gear 166 is held in position on shaft 158 by means of a sleeve 170 which extends from the left-hand end of gear 166 to the right-hand face of the inner raceway of radial bearing 164. Gear 156 is connected to shaft 158 by means of a washer 172 and screw 174, the right-hand end of the hub of gear 156 bearing against the left-hand face of the inner raceway of bearing 164. Gear 166 meshes with gear 102 mounted on the lower end of tower shaft 78.

Thus, referring to Figures 4, 5, 7 and 8, motor 120, acting through pulley 124 and belt 132, drives pulley 128, and thus shaft 134. Shaft 134, acting through worm gear 152 and gear 156 (Figure 7), drives shaft 158. Shaft 158, acting through worm gear 166, drives gear 102, which in turn drives shaft 78 (Figure 12) and thus hat support 46. It will be noted that as the hat support moves toward and from the pouncing pads, a driving connection between the motor and the hat support is maintained at all times, because during this movement of tower 48, the teeth of gear 102 (Figures 7 and 12) simply ride around worm gear 166.

As pointed out hereinabove, tower 48 (Figure 12) is pivotally mounted by means of casting 98 (Figure 7) on the machine so that it may move hat support 46 (Figure 2) toward and from pouncing pads 42 and 44. Tower 48 is at all times biased toward the pouncing pads by means of a spring 176 (Figures 4 and 7) which is connected to an arm 980 (Figure 7a) formed on casting 98 and to a bracket 178 (Figure 4) secured to front casting 56. Spring 176 is under tension at all times, and thus tower 48 is normally biased toward pads 42 and 44. Movement of tower 48 toward and from pouncing pads 42 and 44 (Figure 4) is controlled by control lever 50 (Figure 2).

In general, control lever 50 is connected by means of a hub 180 (Figure 7) to a control shaft, generally indicated at 182. Control shaft 182 has an arm, generally indicated at 184 (Figures 7 and 10), which has a cam groove 184a formed in its right-hand side. An arm. generally indicated at 186, is connected by means of its hub 186a to the right-hand end of casting 98. Arm 186 has a roller 188 mounted on its lower end, which rides in groove 184a (Figures 7 and 10). Arm 184 in Figure 10 is in the position it occupies when the hat support is in inoperative position or in the position it occupies in Figure 2. When lever 50 is moved rearwardly to the position it occupies in Figure 3, shaft 182 is turned in a clockwise direction, as viewed in Figure 10. As arm 184 turns with shaft 182, cam groove 184a is moved to a position at which roller 188 (Figure 10) can move to the left, as viewed in this figure, thus permitting spring 176 (Figures 4 and 7), acting through arm 980, to move tower 48 into operative position.

In detail, shaft 182 is mounted within section 112a of casting 112 (Figures 7 and 7c) upon bearings 190
